printer installs at bootup (Windows XP)

Hi all,

My wife's laptop re-installs the HP inkjet printer every time she boots up her computer. The printer works fine, there is a laser printer connected to the same computer and it does not reinstall each time. She has two printers of the same type installed on her laptop. One is for her home printer and the other is for the printer at her job. They are both the same model number. I tried uninstalling the home printer and just leaving the one copy of the office HP printer on the laptop.

All the printers are connected USB. At home she uses a cradle for her laptop.
